The 125QJP series is a high-efficiency fountain submersible pump specifically engineered for demanding water extraction and decorative fountain applications. Utilizing a high-quality cold-rolled silicon steel motor core, this series ensures superior magnetic conductivity and stable performance during frequent start-stop cycles without overheating, making it an ideal choice for professional water management.
Designed for durability and low maintenance, the 125QJP replaces traditional ball bearings with water-lubricated alloy copper sleeves at the rotor ends. This innovative design effectively eliminates common industry issues such as rust, oil leakage, and abrasive wear, ensuring a longer operational lifespan even in challenging subterranean environments.

Frequently Asked Questions
No, the 125QJP is designed for clean water. Pumping sediment or muddy water is strictly prohibited as it can damage the pump and bearings.
The maximum diving depth for the 125QJP series is 70 meters. Ensure the pump is placed at least 3 meters above the well bottom.
During freezing temperatures, you must drain all water from the motor cavity to prevent ice damage to the pump body.
The standard requirement is a three-phase AC 380V power supply at 50Hz. Custom voltages are available upon request.
Alloy copper sleeves are water-lubricated, which avoids common issues like rust, oil leakage, and wear associated with traditional bearings in submerged conditions.
The pressure regulating film adjusts for expansion and contraction of the internal water caused by temperature changes during operation.
